ITE/Siemens UV421G - 30A, 240V, Fusible Bus Plug

Engineered for reliability in demanding industrial and commercial environments, the ITE/Siemens UV421G Fusible Bus Plug delivers secure power distribution for busway and panelboard systems. With a 30A rating at 240V, it supports essential loads while providing built-in protection to keep critical equipment safe.

What sets the UV421G apart is its integrated fusible design. The fusible bus plug provides overcurrent protection and rapid fault isolation, helping minimize downstream damage and downtime. This makes it an ideal choice for facilities where safety, reliability, and quick maintenance are priorities. Designed for retrofit projects and legacy systems, it fills a niche where compatible, hard-to-source busplugs are required—reducing spare-part complexity and inventory costs.

• Model: UV421G
• Type: Fusible Bus Plug
• Amperage: 30A
• Voltage: 240V
• Applications: Busway and panelboard power distribution systems
• Typical uses: Industrial plants, commercial facilities, process equipment, retrofit projects
• Availability: Ideal for maintenance, repair, and upgrade projects where compatible, hard-to-find busplugs are required

Ideal use scenarios include updating aging distribution networks, adding protective segregation to critical feeders, or stocking a reliable spare for high-uptime environments. It’s well-suited for electricians and maintenance teams working with ITE/Siemens installations, industrial automation setups, and facilities undergoing modernization without sacrificing compatibility or safety.

Practical handling tips: verify that UV421G matches your busway or panelboard footprint, confirm voltage and current requirements, and schedule installation with a qualified electrical professional. When replacing or retrofitting, ensure proper de-energization and follow all safety protocols to maintain system integrity and reliable operation.
